Tumor necrosis factor-like weak inducer of apoptosis (TWEAK/Tnfsf12) is a cytokine implicated in different steps associated with vascular remodeling. However, the role of TWEAK under hyperglycemic conditions is currently unknown. Using two different approaches, genetic deletion of Tnfsf12 and treatment with a TWEAK blocking mAb, we have analyzed the effect of TWEAK inhibition on atherosclerotic plaque progression and stability in streptozotocin-induced diabetic ApoE deficient mice. Genetic inactivation of Tnfsf12 reduced atherosclerosis extension and severity in diabetic ApoE deficient mice...

Type 2 diabetic patients are known to have a tendency to develop cardiovascular (CV) disease (CVD), and related unfavourable outcomes such as heart failure, myocardial infarction (MI), cerebrovascular events (eg. stroke), and related mortality. Long- term clinical trials have revealed contradictory findings regarding the relationship between glycemic control and CV benefits due to variations in the key characteristics of the study population. During the last decade, number of pharmacological agents used for glucose- lowering in the treatment of type 2 diabetes mellitus (T2DM) has increased owing to the introduction of dipeptidyl peptidase- IV (DPP- IV) inhibitors, glucagon- like peptide- 1 (GLP- 1) receptor agonists, and sodium-glucose co-transporter 2 (SGLT- 2) inhibitors...

PURPOSE: The implementation of pharmacist-managed insulin dosing for selected hospitalized patients under a multimodal insulin protocol (MMIP) is described. SUMMARY: Hyperglycemia has been linked to increased thrombosis, decreased wound healing, and decreased immune response. Current recommendations support the use of multimodal (basal-bolus) insulin therapy in noncritically ill inpatients. As part of a systemwide quality-improvement initiative to improve glycemic management, the pharmacy department of a community hospital initiated a service to provide protocol-directed insulin dosing for selected patients under a pharmacist consultation model...

BACKGROUND & AIMS: Depletion of interstitial cells of Cajal (ICCs) is common in diabetic gastroparesis. However, in approximately 20% of patients with diabetes, gastric emptying (GE) is accelerated. GE is also faster in obese individuals, and is associated with increased blood levels of glucose in patients with type 2 diabetes. To understand the fate of ICCs in hyperinsulinemic, hyperglycemic states characterized by rapid GE, we studied mice with mutation of the leptin receptor (Lepr(db/db)), which in our colony had accelerated GE...

As perioperative hyperglycemia is associated with poor postoperative patient outcomes, clinical guidelines provide recommendations for optimal perioperative glucose control. It is unclear to what extent recommended glucose levels are met in daily practice, and little is known about factors that influence these levels. We describe blood glucose levels throughout the hospital care pathway in 375 non-critically ill patients with diabetes who underwent major surgery (abdominal, cardiac, or orthopedic) in 6 hospitals, examine determinants of these levels including adherence to 9 quality indicators for optimal perioperative diabetes care, and perform qualitative interviews to identify barriers for optimal care...

Therapeutic effects of mesenchymal stem cell (MSC) infusion have been revealed in various human disorders, but impacts of diseased micro-environments are only beginning to be noticed. Donor diabetic hyperglycemia is reported to impair therapeutic efficacy of stem cells. However, whether recipient diabetic condition also affects MSC-mediated therapy is unknown. We and others have previously shown that MSC infusion could cure osteopenia, particularly in ovariectomized (OVX) mice. Here, we discovered impaired MSC therapeutic effects on osteopenia in recipient type 1 diabetes (T1D)...

AIMS: The use of continuous subcutaneous insulin infusion (CSII) in type 1 diabetes (T1D) has increased in recent years. Sensor-augmented pump therapy (SAP) with low glucose suspend (LGS) (allowing temporary suspension of insulin delivery if blood glucose level falls below a pre-defined threshold level) provides additional benefits over CSII alone, but is associated with higher acquisition costs. Therefore, a cost-effectiveness analysis of SAP+LGS versus CSII in patients with T1D was performed...

Orexigenic hormone ghrelin and anorexic hormone obestatin are encoded by the same preproghrelin gene. While it is known that ghrelin inhibits glucose-stimulated insulin secretion (GSIS), the effect of obestatin on GSIS is unclear. Ghrelin's effect is mediated by its receptor Growth Hormone Secretagogue Receptor (GHS-R), but the physiologically relevant receptor of obestatin remains debatable. Here we have investigated the effect of obestatin on GSIS in vitro, in vivo and ex vivo, and tested whether obestatin regulates insulin secretion through GHS-R...

AIM: To study atherosclerosis risk in diabetes, we investigated ATP-binding cassette transporter A1 (ABCA1) expression and high-density lipoprotein (HDL) biogenesis in the liver and hepatocytes under hyperglycemic conditions. METHODS AND RESULTS: In streptozotocin-induced diabetic mice, plasma HDL decreased while ABCA1 protein increased without changing its mRNA in the liver, only in the animals that responded to the treatment to show hypoinsulinemia and fasting hyperglycemia but not in the poor responders not showing those...

Renal glucose reabsorption was measured with the stepped-hyperglycemic clamp in 15 T2DM and 15 non-diabetic subjects after 2 days and after more chronic (14 days) treatment with empagliflozin. T2DM patients had significantly greater maximal renal glucose transport (TmG) compared to nondiabetic subjects at baseline (459±53 vs 337±25 mg/min, p<0.05). Empagliflozin treatment for 48 hours reduced the TmG in both diabetic and non-diabetic individuals by 44±7% and 53±6%, respectively (both p<0.001). TmG was further reduced by empagliflozin in both groups on day 14 (by 65±5% and 75±3%, respectively)...

Aggregation of the amyloid beta (Aβ) peptide and hyperphosphorylation of tau protein, which are markers of Alzheimer's disease (AD), have been reported also in diabetes mellitus (DM). One regulator of tau phosphorylation is O-GlcNAcylation, whereas for hyperphosphorylation it could be GSK3beta, which is activated in hyperglycemic conditions. With this in mind, both O-GlcNAcylation and phosphorylation of tau protein were evaluated in the brain of rats with streptozotocin (STZ)-induced hyperglycemia and hyperinsulinemia and treated with the Aß25-35 peptide in the hippocampal region CA1...

The aim of this study was to assess the hypoglycemic and antihyperglycemic activities of nine plants used as antidiabetic treatments in Lubumbashi and its surroundings. Those are Albizia adianthifolia, Azanza garckeana, Cassia occidentalis, Cassia sieberiana, Erythrina abyssinica, Gladiolus klattianus, Rauvolfia caffra, Strychnos spinosa, and Vitex madiensis. Aqueous extracts, obtained by decoction and maceration, were administered (500 mg/kg) per os to guinea pigs (Cavia porcellus), both in glucose baseline conditions and in oral glucose tolerance test (OGTT) conditions (glucose, 2 g/kg; follow-up over 210 min)...

A dried infusion prepared from the aerial parts of Salvia circinata did not provoke acute toxicity in mice (LD50 > 5 g/kg). This infusion showed poor hypoglycemic and antihyperglycemic effects (100-570 mg/kg) when tested in normal and hyperglycemic mice using acute and oral glucose tolerance tests, respectively. However, this infusion possessed antihyperglycemic action in vivo during an oral sucrose tolerance test (31.6-316 mg/kg), suggesting the presence of α-glucosidase inhibitors in S. circinata. Fractionation of a nonpolar extract of the aerial parts of the plant yielded a new biflavone (1) and four new neoclerodane diterpenoid glucosides (2-5) along with the known compounds amarisolide (6), pedalitin (7), apigenin-7-O-β-d-glucoside (8), and the flavone 2-(3,4-dimethoxyphenyl)-5,6-dihydroxy-7-methoxy-4H-chromen-4-one (9)...

BACKGROUND: Pancreatic beta cells are unique effectors in the control of glucose homeostasis and their deficiency results in impaired insulin production leading to severe diabetic diseases. Here, we investigated the potential of a population of nonadherent muscle-derived stem cells (MDSC) from adult mouse muscle to differentiate in vitro into beta cells when transplanted as undifferentiated stem cells in vivo to compensate for beta-cell deficiency. RESULTS: In vitro, cultured MDSC spontaneously differentiated into insulin-expressing islet-like cell clusters as revealed using MDSC from transgenic mice expressing GFP or mCherry under the control of an insulin promoter...

Persicarin is one of the major components of the Oenanthe javanica (water dropwort). The present study was aimed to evaluate the role of persicarin in the hepatic tissue of streptozotocin-induced type 1 diabetic mice. Diabetes was induced by single intra-peritoneal injection of streptozotocin (120 mg/kg body weight) and then oral administration of persicarin at a dose 2.5 and 5 mg/kg body weight for 10 days. Serum and hepatic glucose levels were increased in diabetic control mice, while persicarin treatment groups were markedly reduced...

Higher plasma uric acid (PUA) levels are associated with lower GFR and higher blood pressure (BP) in patients with type 1 diabetes (T1D). Our aim was to determine the impact of PUA lowering on renal and vascular function in patients with uncomplicated T1D.T1D patients (n=49) were studied under eu- and hyperglycemic conditions at baseline and after PUA lowering with febuxostat (FBX) for 8 weeks. Healthy controls (HC) were studied under normoglycemic conditions (n=24). PUA, GFR (inulin), effective renal plasma flow (ERPF, paraaminohippurate), BP and hemodynamic responses to an infusion of angiotensin II (assessment of intrarenal RAAS) were measured pre- and post-FBX...
